Fix redfish_facts GetPsuInventory command not returning correct output (

ansible#52675)

* Move GetPsuInventory from Systems category to Chassis category

* Change get_psu_inventory to search through Chassis instead of Systems and PoweredBy for PowerSupplies

* Remove GetPsuInventory from Examples

* remove trailing whitespace

* Change boolean check from '!= None' to 'is not None'

* Don't include 'Absent' PSUs in get_psu_inventory()

* Add check to see if Power key is in Chassis before proceeding

* remove trailing whitespace

* Add continue step for when powersupply property is not found, and check if resulting entries is empty, returning message if nothing was found rather than an empty list
